Replace an undocumented example by a cookbook page

[karlnapf]

Add a single page in the cookbook, replacing a python/octave/ ... example.

The patch should contain 3 changes

• added .rst file
• added .sg file
• remove .py, .m, ... files

See https://github.com/shogun-toolbox/docs/blob/master/EXAMPLES.md and https://github.com/shogun-toolbox/docs/blob/master/DEVELOPING.md for instructions.

NOTE: There are many many of those, so this needs many people solving small pieces

Ok, I've given it a shot for the Gaussian Naive Bayes example. I'm new to Shogun (and ML in general), so I would really appreciate it if someone could give it a quick look and let me know if everything looks ok.

Hi there,
great, these are exactly the two files we need. Please send a Pull request against the cookbook feature branch (link above) rather than posting the files here. I will review it in there then.

A note for the others -- there are many more examples to go

@karlnapf I tried to build the cookbook in doc/cookbook/build by doing cmake .. and make cookbook. I tried the same in shogun's build dir also. Here is the error gist.
cmake -DBUILD_META_EXAMPLES .. is also not working. What am I missing?

[karlnapf]

This is just the link checker failing, are you online?
Also pull the latest version, it works on my machine

[ballardt]

Hmm, pretty sure I would have been online, but I'm using a stock Broadcom card that frequently acts up with Linux, so my connection probably went down at some point.
Btw I've been busy with some school assignments, but I should be able to remove those unnecessary bits from the cookbook page either today or tomorrow. 
Thanks!

@karlnapf It works now after pulling the latest version. Although cmake -DBUILD_META_EXAMPLES .. is still not working. The cookbook looks pretty neat.

[karlnapf]

@tbskm I like the gaussian naive bayes example! Will merge soon.

[karlnapf]

@sanuj lets not discuss this here ... irc maybe?

Hello, I'm working on replacing "converter_multidimensionalscaling_modular.py" with a meta example and a cookbook page.

I have created a "converter" subdirectory under "examples/meta/src" and am thinking of adding a "Feature Transformations" (inspired from "converter") field in index.rst. Truth is that MDS is a general technique that can be applied for visualization, dimensionality reduction or feature extraction, so I'm skeptical about the correct name, do you have any suggestions?

I also have a problem with this line of code
return numpy.linalg.norm(distance_matrix_after-distance_matrix_before)/numpy.linalg.norm(distance_matrix_before) < 1e-6

How should this appear in the .sg file? Building as
bool output = ((numpy.linalg.norm(distance_matrix_after-distance_matrix_before) / numpy.linalg.norm(distance_matrix_before)) < 1e-6) shows that the math operators are not used correctly. Any resources on this? To my knowledge no existing example uses a math operator other than =.

[karlnapf]

All good. I commented that we will not have this norm comparison in the output. That is unit testing material and the meta examples just store the results, so just remove the line

[karlnapf]

Whoops. Re-opening as there are lots of python example still.

No need for cookbook rst pages for the remaining distance examples. A meta example is fine.
